Left foot forwards, right handed grip

Hi. I've got a slight problem with my Judo stance. I much prefer to have me left foot fowards, it just feels more natural. Unfortunately, I also prefer a right handed grip. I've been doing Judo for 5 months or so and I think I should correct this problem before becomes permanent. Do I need to change my stance? Thanks!

Assuming you're a white belt or on the white side of green belt. It's going to be best for your long term development, to learn to stand 'Judo style' rather than train yourself to switch dominant hands.

All the muscle and co-ordination you'll have developed in your upper body due to striking right handed will be un-done if you switch to grappling left handed.

Yeah, hane goshi was my tokui waza 50 years ago but it demonstrates at least one of a few techniques using the method you describe, so use it to your advantage. It is a difficult technique and in a few years you may master it.
